What's beef?

It seems a a bit of Twitter beef has been sparked between Rihanna and actress Amanda Bynes. The latter was the instigator, who, unprovoked, tweeted "Chris Brown beat you because you're not pretty enough" and "no one wants to be your lover so you call everyone and their mother that I almost named my new dog Rihanna."

Bynes quickly deleted the offending tweets, but Rihanna still found out about them, of couse. She responded simply: "Ya see what happens when they cancel Intervention?" The singer is not one to remain silent when it comes to slander.

This incident comes just three days after Bynes was arrested at her apartment on West 47th Street in Manhattan for criminal possession of marijuana, tampering with evidence and reckless endangerment. She apparently tossed a glass bong out of her 36th floor window after a complaint from the doorman.

Amanda Bynes is claiming that the screen shot of her allegedly deleted Rihanna-bashing tweets is a fake image. The star went on another one of her signature 140-character eclipsing rants that argued that she did not take shots at the singer, and actually expressed interest on working on music with RiRi in the future.

"I saw a bunch of mocked up tweets about me bashing Rihanna in my mentions. I'm followed by so many people that someone is always mocking up fake tweets so I feel the need to address them! Rihanna and I met and I'm sure we'll be in a music video together one day! That's one of the mocked up images, they took photos of me from outside and morphed them onto someone else's body."

Waka Flocka Flame has also gotten involved in the mayhem, first tweeting an ellipsis at Bynes (most likely expressing the same confusion that many are experiencing from her recent antics), but later providing her with some advice in the form of a #FlockaFact. "when people hate and the media lies……. That means you popping" he tweeted in support.
